Your mystery number will be x.

5+3x=5x-8

If you only want the equation, there it is. If you want me to solve as well, just say the word.

I already answered, but if you can't see it for some reason, the answer is A.

3x+5=5x-8

 

And if you want it solved, then here it is.

3x+5=5x-8

Add 8 to both sides.

3x+13=5x

Subtract 3x from both sides.

13=2x

Divide both sides by 2

\(x=\frac{13}{2}=6.5\)

3N + 6  =  5N - 4    add 4 to both sides, subtract 3N from both sides

 

10  =  2N      divide both sides by   2

 

5  = N  ⇒      answer B

 

 

 

cool cool cool
